Expected behavior

Builds successfully. This same project worked a couple months ago before re-cloning it.

Additional information

使用 platformio.ini 配置重现该失败，并检查 .pio/libdeps/pico/micro_ros_platformio/build/mcu/src/Micro-XRCE-DDS-Client/src/c/util/time.c 的第 71 行。追踪 microxrcedds_client 的构建输入和工具链假设；当 humble pico 环境能够在没有 clock_gettime 错误的情况下成功构建时，即表示完成。
